Designed by IA Interior Architects, Mesirow Financial’s headquarters at 353 North Clark Street in Chicago uses the Lutron Quantum light control system along with demountable walls, allowing occupants to rearrange teams at a lower cost.

Slated for completion in 2015, the Gensler-designed PNC Headquarters is designed so that 91 percent of the floor plate has access to natural light—typical floor designs have natural light coverage closer to 67 percent.
